Application March .21, 1941, Serial No; 384.438 2 Claims; (01. 88-39) YMy invention relates to a new and usefulim provement in a flash lightattachment adapted particularly for use on the pencil type flash lightsflash light is' provided .with th necessary means I for turning thesameon and off, and projecting which are of very small diameter andmaybe carried in the pocket similarto a pencil.

In the use of a flash light it is frequently necessary to magnify theobject on which the light is directed. Particularly is this soin'reading small usedfor securingthe device inthe pocket. FTh eoutwardly from the forward end thereof is the light bulb l1. ,Embracingthe body of the flash light I4 is a collar or sleeve I3 provided with'knurling 19 for facilitating the slidable movea merit of the collar onthe body'ofthe flash light. As shown in Fig. 5 this collar is is splitand pref! print and especially in reading gas meters and electric metersand the like located indark places. The device is also adapted for us inreading matter in small print and particularly adapted for use bymilitary omcers in reading maps and the like. The inventionhas alsoproven itself quite eflicient in food inspection operations, per-.

mitting the food to be illuminated and, at the same time, magnifiedwhile being examined.

It is an object of thepresentinvention to provide a flash light equippedwith magnifying means so constructed and arranged and mounted on theflash light that it may be easily and quick: 1y moved to position foruse" and moved to non usable position, while, at the same time, the sizeof the flash light itself is substantially unaffected.

It is another object of the presentinvention to provide a device of thistype, which will be simple in structure, economical of manufacture,durable, compact, easily and quickly mountable in position and removedtherefrom and one which will be highly eflicient in use. Other objectswill appear hereinafter. Itis recognized that various departures fromthe detail of structure illustrated may be made without departing fromthe invention, and it is intended that such modifications and variationsmay be embraced within the scope hereof.

erably formedofresilient material so that it will securely grip the bodyof the flash light and be retained at the positions in" which it ismoved; It is believed obvious that if desired, a freely slidable sleevemay be moved withfa rocking mechanismsuch'as a boss and recessassociated with the'bodyand sleeve or collar for securingv the structurin various positions of movement;

Extending outwardly mm the sleeve. or ,eollar l9; is an 'arcuate platewhich in reality forms a continuation o'f the sleeve orvcollar. An open11 7 ing 2i formed in this plate 20. and mounted in this opening is amagnifying lens 22.

The construction. is such th t when the flash light is carried-in thepocket the sleeve I8 is slid into the position Fig. 1, so thatthe plate29 lies within the end limits of the flash light-body. This structure ispreferably made from very thin metal or'plastic material so that thesize of the body'pf th'e'i'lash lightis substantially unaltered 7 sothat no bulky'structure is built up to prevent the easy carrying of theflash light in th pocket,

7 When desired to use the magnifying feature of a 1 the invention, thesleeve or collar 1 8is'slid toward Forming a part of this specificationis'a draw:

ing in which:

Fig. 1 is a side elevational view showing a magnifying lens in aninoperative position.

Fig. 2 is a view similar to'Fi'g. 1 showing the magnifying lens inoperative position.

Fig. 5 is a perspective view of the slidable attachment. I r

Fig. 6 is a fragmentary side elevational view of a slightly modifiedform of the invention with parts broken away and parts shown in section.

Fig. 7 is a sectional view taken on line 1- -1 of Fig. 6. V V

In the drawing I have illustrated the flash light l4 provided with aspring clip I6 which may be the forward end of the body as shown in Fig.2, therewith the magnifying lens 22 overlies the area directly in frontof the'bulb i1; thus it becomes possible to illuminatthe'material'whi'ch 1 is visible through the magnifying lens 22 and 3the advantagessought are thus obtained.

1 In Fig. 6 I have shown a slightly modified form --ofconstruction inwhich the collar or sleeve 7i 3" 7 is'fixedly mounted on'the body of theflash light v M and the plate 20 is dispensed with. Pivotally mounted bymeans of-theipivot pin 23 on the collar I8 is a swingable plate- 2i!having an opening 2| formed therein inwhich is mounted the magnifyinglens 22. When it is desired to use the invention the plate 26:. is swunginto full" line position shown, in Fig. 6. so that this plate extendbeyond the forward endof thefiash light -retaining the mag'nifying'lens22 over the area which may be illuminated by the light bulhl'lfl;

When the flashlight is not in use the plate 20f may be swungaround intothe dotted line position shown in Fig. 6 so as to lie within the mar-k"ginal limits of the body of the flash light M; In both types ofstructures it will b noted'that the magnifying lens, when in inoperativeposition, lies within the marginal limits of the flash light H. The useand operation of the modified Y form is similar to the form'shownin'Fig. 1, the method of mounting being slightly altered.

What I claim as new ist bulb bearing end of said body; and a magnifying1 lens mounted in said opening and overlying the 1. In combination witha flash light having a1 body and a light bulb in oneend thereof, a splitresilient sleeve embracing and slidably mounted on said body; a curvedextension plate projecting forwardly from said sleeve and movableinunison,

therewith and having an opening formed therein and adapted for lyingbetween the ends of said body andv for being projected beyond the lightsaid knurled portion, said extensionmember hav-' ing a window therein inwhich is secured a magnifying lens, said extension member and said lensbeing curved to closely conform to the con- .7 tour of the flashlightbarrel. i a.
